Zaxby's Franchising Inc. said in a statement that the suspicious files may have resulted in unauthorized access to credit and debit card information at more than 100 stores.

The Athens-based firm says the affected stores are in Alabama, Arkansas, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, Mississippi and Virginia.

The company says it notified law enforcement of the potential criminal activity. Zaxby's says a forensic investigation hasn't determined whether credit or debit card data left the processing systems of any stores.
